Hi!
I just finished the import of grep-2.5 into the NetBSD base system.
Please note that the '-o' option that we had for 4.4BSD compatibility
is now obsolete (use '-H' instead).
The reason is that GNU grep added a -o option:
-o, --only-matching
Show only the part of a matching line that matches
PATTERN.
grep is now using nearly every letter in the alphabet as option,
so this was only a question of time...
Cheers,
Thomas
